selecting items in linked model

[james.levieux]

After items in a linked model the UIdocument.Selection.GetElementIds() yeilds nothing.  As a work-around, I've toyed with UIdocument.Selection.PickObjects() which does return an IList<Reference> which is an improvement!

I want to be able to hide some linked elements depending on their properties.  The problem is that I can't figure out how to access the elements using the Reference objects I've acquired.  What is the purpose of the CreateLinkReference  method and how can I acquire the RevitLinkedInstance object to use it?  I feel like I'm stabbing blindly into the dark.

Can anyone explain how to use these reference objects?

Here is an example of selecting a linked element: 

#Current document
doc = revit.doc
uidoc = revit.uidoc
#Collect the linked instances, grab the first instance in the list
linked_instance = FilteredElementCollector(doc).OfClass(RevitLinkInstance).ToElements()[0]
# Get linked document from instance
linked_doc = linked_instance.GetLinkDocument()
#Ask User to select linked element
linked_reference = uidoc.Selection.PickObject(ObjectType.LinkedElement, "Pick Linked Element")
#Get Linked element from linked document
linked_element = linked_doc.GetElement(linked_reference.LinkedElementId)
#Hide or do something with element ...

That does the trick. Thank you! Disappointed to find that I can't hide the element once I've acquired it!
